some usb disk such as Manufacturer Lenovo will have some problem in
init process.
when it run "scsi_dh_find_driver" function, because this parameter of
"sdev->inquiry[5]" is 115, it will return "alua" in "scsi_dh_find_driver"
function and will have some error log (alua: Attach failed (-22)). some
usb init will fail and isn't used.
